We consider dark matter haloes formed from progenitors that have undergone no star formation as a result of early reionization and photoevaporation caused by a nearby galaxy. Once such a halo reaches ≈109 M⊙, corresponding to the Jeans mass of the photoheated intergalactic medium at z ≈ 7, pristine gas is able to collapse into the halo, potentially producing a massive Pop III starburst. We suggest that this scenario may explain the recent observation of strong He ii 1640 Å line emission in CR 7, which is consistent with ∼107 M⊙ of young Pop III stars. Such a large mass of Pop III stars is unlikely without the photoionization feedback scenario, because star formation is expected to inject metals into haloes above the atomic cooling threshold (∼108 M⊙ at z ≈ 7). We use merger trees to analytically estimate the abundance of observable Pop III galaxies formed through this channel, and find a number density of ≈10−7 Mpc−3 at z = 6.6 (the redshift of CR 7). This is approximately a factor of 10 lower than the density of Ly α emitters as bright as CR 7.","lang":"eng"}],"title":"Formation of massive Population III galaxies through photoionization feedback: A possible explanation for CR 7","extern":"1","_id":"17654","volume":460,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-06T07:32:23Z","author":[{"full_name":"Visbal, Eli","first_name":"Eli","last_name":"Visbal"},{"last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","full_name":"Haiman, Zoltán"},{"first_name":"Greg L.","full_name":"Bryan, Greg L.","last_name":"Bryan"}],"page":"L59-L63","issue":"1","language":[{"iso":"eng"}],"article_type":"original","date_published":"2016-04-14T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.1093/mnrasl/slw071","open_access":"1"}],"status":"public","day":"14","oa_version":"Published Version","citation":{"apa":"Visbal, E., Haiman, Z., &#38; Bryan, G.
